Intensity KJ

Lightweight and agile, the Intensity is made for athletes who move fast and need their vision to keep up—and the Kilian Jornet Series edition pairs that performance DNA with a colorway rooted in the Norwegian landscape Kilian calls home. The matte brown frame is accented with sandstone and glacier blue details that mirror the quiet, rugged beauty of Scandinavian terrain.
This edition is equipped with a REACTIV 1-3 HIGH CONTRAST lens, a photochromic lens that adapts from low light to bright sun while enhancing contrast and depth perception—ideal for reading trail surfaces, roots, and rocks at speed. Whatever the conditions throw at you, your vision adjusts without missing a beat.
The Intensity's panoramic lens delivers a wide, unobstructed field of view, while Grip-Tech temples provide the stay-put security you need through sweat, technical descents, and long miles. Helmet-compatible and built for cycling and trail running, this is a sunglass designed to disappear on your face and let the terrain take center stage.
Every pair in the Kilian Jornet Series comes with a signature Kilian Jornet pouch with an attached microfiber cloth for cleaning and storage.
